At 1.4038%, Stone Mills sits 226 of 386 Ontario municipalities ranked cheapest to most expensive — 4% above the provincial median of 1.3516%. On a $500,000 assessment that works out to $7,019 a year, or $585 a month.
Stone Mills has already filed 2025: 1.4582% total, +3.87% against 2024 — $7,291 on a $500,000 assessment. Rankings on this site still use 2024, because only 282 of 386 municipalities have filed 2025 so far and a partial year would make every rank meaningless.

A rate rising while the base also grows means the budget grew faster than property values; a rate falling while the base grows usually means the opposite.

They are not, measured against the rest of the province. Stone Mills's total rate of 1.4038% sits close to the Ontario median of 1.3516%, ranking 226 of 386. A bill can still feel high when the assessment is high, because the rate is only half of the calculation.
Stone Mills’s total residential tax rate is 1.40%, 8% above the middle lower-tier municipality (1.30%).
Of that rate, 0.58% goes to Lennox and Addington County and 0.15% to schools; 0.67% is set by Stone Mills itself.
Homes here carry $239,469 of assessed value per household, 13% below the middle ($275,612). Lower values mean it needs a higher rate to raise the same money.
It spends $3,165 per household in total, 23% below the middle ($4,124). The biggest gaps above the middle: roads and bridges (+$586). Below: parks and recreation (−$237), running the municipality (−$166).
Across 226 lower-tier municipalities, rates move more with home values (rank correlation -0.72) than with spending per household (0.45). That is a pattern, not proof of cause.
Closest on total tax rate, assessment / household, spending per household, population, 5-year growth, people per household, among municipalities of the same tier.
Stone Mills reported a residential assessment base of $1B for 2024 and collected $13M in residential property tax against it. Assessment is the figure on the MPAC notice, still based on 2016 valuations province-wide, which is why it usually differs from what a house would sell for today.
These are the figures Stone Mills filed with the province. An individual bill can include area-specific charges and local improvement levies that a municipality-wide rate does not capture. Reference, not tax advice.
